Active area is indeed the size you can draw on. That section on the Wacom site has an error. It looks like you selected medium, but it’s still giving you dimensions for the small. 6 x 3.7 inches is the dimension of the active area for the intuos art/comic/photo small.
Your Wacom Graphire Bluetooth
Dimensions: 11.5 x 10.5,
Active area: 6 x 8 inches
Small Wacom Intuos Art/Comic/Photo (All the same tablet, different bundled stuff)
Dimensions: 8.25 x 6.7,
Active area: 6 x 3.7
Medium Wacom Intuos Art/Comic/Photo
Dimensions: 10.75 x 8.75,
Active area: 8.5 x 5.3
The old tablets were the Bamboo and Intuos. The former being the hobbyist tablets, and the Intuos 2, 3, 4, 5 aimed at the professional market. But they changed the name a few years back. The Bamboo became the Intuos series, and the Intuos series became the Intuos Pro series.
Now they’ve released a new set of tablets, but they didn’t add numbers to them, so look out for anything labelled (OLD MODEL) on Amazon, unless you specifically want the previous release.
Confusing huh? 🙂
tl;dr The Intuos Art Medium has an active area of 8.5 x 5.3. Wacom’s site is wrong.
Edit – good formatting is hard here, sorry about the mess.
